The Amusement Park series from Knex lets you build a working amusement park in your own home.
This Corkscrew set includes over 300 pieces that will make up the working rollercoaster which can be reused to make anything you want. This rollercoaster has a great winch system that will bring the carriages to the top before dropping them in freefall. Consisting primarily of micro rods, the set comes with a working electric motor to power your creations. With bright pieces that will look great when the Corkscrew is finished, the Knex kit will inspire you to build and build.
Requires 2x AA batteries.
